Descriptor:
Damage
Description:
Roots injured by low temperatures usually do not produce latex when cut.  Internally the flesh may be spongy and watery and later develop cavities and dark color.  Notice blackening of veins.  Presence of Penicillium on the surface often indicates cold injury (cv.Jewel, May78).
